  • the width is 155 cm
  • the viscose content is 70% (part by weight)
  • the polyamide content is 30% (part by weight).

  • the gram weight is 200 g/m2
  • the width is 160 cm
  • the viscose content is 60% (part by weight)

  • the polyester content is 30% (part by weight).
  • This example provides a fabric with cool feeling function, and its weaving process is as follows:
  • Example 1 The difference between the production process and that of Example 1 is that no hydrophilic silicone oil is added in a process of the shaping.
  • the gram weight is 180 g/m2
  • the width is 155 cm
  • the viscose content is 70% (part by weight)
  • the polyamide content is 30% (part by weight).
  • the fabric weaving process and production process of this comparative example are the same as those in Example 1, and the finished fabric specifications are also the same, but the thermally conductive yarn used is acrylic fiber, with the conventional moisture regain of 2%, and the coefficient of thermal conductivity of 0.051 W/(m ⁇ K).
  • the fabric weaving process and production process of this comparative example are the same as those in Example 1, and the finished fabric specifications are also the same, but the difference is that the yarn used is mainly made from polyamide fiber and added with a cool-feeling functional yarn made from mica.
  • the fabric weaving process and production process of this comparative example are the same as those in Example 1, and the finished fabric specifications are also the same, but the difference is that the yarns used are all polyamide fibers, and the final fabric is processed by dipping with a xylitol cool-feeling finishing agent.
  • Cool feeling test Qmax test method, in accordance with the national standard GB/T35263-2017 “Textiles—Testing and evaluation for cool feeling in contact instant” implemented on Jul. 1, 2018.
  • the standard specifies the testing and evaluation methods for cool feeling performance of textiles in instant contact with the skin, which is applicable to all kinds of fabrics and their products.
  • Test principles include: under the specified test environmental conditions, contacting the thermal detection plate with a temperature higher than the sample with the sample, measuring the temperature change of the thermal detection plate with time, and calculating its contact cool-feeling coefficient (Qmax), which can characterize the instant cool feeling performance of the sample.
  • the contact cool-feeling coefficient Qmax refers to the maximum value of the heat flux density during the heat transfer process after the thermal detection plate with a temperature higher than the specified temperature difference of the sample is contacted with the sample at a certain pressure, with the unit represented by a heat flow (W/cm2) of the instant cool feeling of the fabric.
  • the larger the Qmax value is, the stronger the cool feeling is on the skin, and the smaller the Qmax value is, the weaker the cool feeling is on the skin ( ⁇ T 15° C.).
  • the overall cool feeling is gradually increasing from 1 to 5 grades. Specifically, grade 1 represents no cool feeling, grade 2 represents slight cool feeling, grade 3 represents good cool feeling, grade 4 represents comfortable cool feeling, and grade 5 represents very comfortable cool feeling.
  • the fabric with cool feeling function produced by this method has an excellent cool feeling function; the specific performance is that the Qmax of the fabrics in the examples before washing and after 10 washings are always above 0.15, which improves the cooling comfort of the fabrics as a whole. Furthermore, compared with other preparation methods of cool-feeling fabrics (Comparative Examples 6-7), the Examples reduce the production cost, shorten the production process, save resources, and conform to the trend of environmental protection and energy saving.
  • Example 1 the viscose has a high conventional moisture regain of 13%, and the polyamide has a high coefficient of thermal conductivity of 0.244-0.337 W/(m ⁇ K).
  • the research results of the international journal “Artificial Fiber” shows that: when the water content of the human skin surface is 12%-15%, the skin comfort is the best; in order to ensure 12%-15% moisture of human skin, it is correspondingly required that textile fibers in contact with human skin must have a moisture absorption rate of 12%-15%. Furthermore, the conventional moisture regain of polyamide is 4.5%, which is 8.5% different from that of viscose. Test results have shown that the fabric prepared under this difference has an excellent cool feeling, and the overall cool feeling is grade 5. The viscose adopts compact siro spinning.
  • the yarn hairiness obtained by compact siro spinning is less, and the evenness is better.
  • the yarn is clean and smooth, which is more conducive to the improvement of the cool feeling.
  • the polyamide is drawn yarn, and the polyamide is filament, where the fiber yarn itself is relatively smooth and flat, and the fully drawn yarn is selected.
  • the drawn yarn which is straightened after being stretched is not bent, which reduces the space for air to stay, increases the contact area, improves the thermal conductivity, and can improve the cool feeling.
  • a softener added in the process of shaping can improve the hydrophilicity and hygroscopicity of the polyamide yarn material, which is more conducive to the polyamide to transmit the absorbed moisture to the viscose yarn with good hygroscopicity. Moisture conduction takes heat away at the same time, which increases the cooling effect.
  • the added softener can also increase the soft and smooth feel of the fabric and increase the cooling effect.
  • Example 2 The ordinary plain weave structure is adopted in Example 2, hence, compared with the plaiting stitch, the contact area between the fabric and the skin of Example 2 is not as good as that of the fabric of Example 1, so the cool feeling is not as good as that of Example 1, and the overall cool feeling is grade 4.
  • Example 3 The yarn count of the thermally conductive yarn in Example 3 is slightly thicker than that in Example 1, and the thermal conductivity effect is slightly better than that in Example 1. Although the overall cool feeling in Example 3 is the same as grade 5, the parameter of Qmax is slightly higher than that of Example 1.
  • Example 4 since the hygroscopicity of cotton is lower than that of viscose, the thermal conductivity of the thermally conductive yarn polyester is lower than that of polyamide, the overall cool feeling is lower than that of Example 1, and the overall cooling is grade 3.
  • Example 5 no hydrophilic silicone oil is added, and the hygroscopicity of polyamide is not further improved; although the thermal conductivity is good, the moisture transfer performance is poor, and the heat conduction effect is not as good as that of Example 1, so the cool feeling is slightly worse than that of Example 1, and the overall cool feeling is grade 4.
  • Example 6 First Comparative Example, the simple hygroscopic material viscose has moderate thermal conductivity, and the capability of the fabric to transmit heat decreases, which has a greater impact on the cool feeling, and thus the cool feeling effect is significantly reduced, and the overall cool feeling is grade 2.
  • Example 7 (Second Comparative Example), the simple thermally conductive material polyamide has average hygroscopic performance, and thus the cool feeling is not as good as that of Example 1, and the overall cool feeling is grade 2.
  • Example 8 (Third Comparative Example), the thermal conductivity of polyester is not as good as that of polyamide, and the moisture absorption performance is poor, and thus the cool feeling is poor, and the overall cool feeling is grade 2.
  • Example 9 Although wool yarn has high hygroscopicity, its thermal conductivity is too low, and the cool feeling of the overall fabric is not good.
  • the overall cool feeling before washing is grade 3, but after the wool is washed for many times, the cool feeling decreases, and the overall cool feeling drops to grade 2.
  • Example 10 (Fifth Comparative Example, the acrylic fiber yarn has poor thermal conductivity and poor moisture absorption performance, and the overall cool feeling of the fabric is not good, and its overall cool feeling is grade 2.
  • Example 11 (Sixth Comparative Example), the thermally conductive yarn is mainly made from polyamide fiber and added with a cool-feeling functional yarn made from mica.
  • the cool-feeling function is equivalent to that of Example 1, and the overall cool feeling before washing is grade 5.
  • the production cost is relatively high.
  • the unstable mica reagent on the surface of the cool-feeling functional yarn will also fall off, causing the cool feeling to decrease, and the overall cool feeling decreases to grade 4.
  • Example 12 when finishing, the xylitol cool-feeling finishing agent is used to achieve cool feeling function, the obtained cool feeling is good, and the overall cool feeling before washing is grade 5. However, after washing with water or increasing the number of washings, after the xylitol cool-feeling finishing agent on the surface is rinsed, the cool feeling is weakened, and the overall cool feeling decreases to grade 3.
  • a fabric with cool feeling function comprises a first fabric layer and a second fabric layer, where the first fabric layer is formed by interweaving hygroscopic yarn materials, and the second fabric layer is formed by interweaving thermally conductive yarn materials; the first fabric layer and the second fabric layer are connected through knotting spots formed by interweaving the hygroscopic yarn materials of the first fabric layer and the thermally conductive yarn materials of the second fabric layer.
  • the fabric with cool feeling function, related cloth and clothing items and a manufacturing method and systems thereof employ a layered structure weaving method, and the interaction between the hygroscopic yarn materials and the thermally conductive yarn materials to continuously produce cool feeling effects. It is not necessary but it is possible to add additional processes in a dyeing and finishing process, which is the same as the conventional dyeing and finishing process of fabrics, that is, it can give the prepared fabrics a cool feeling function.
  • Most of the yarns used in the fabric with cool feeling function, related cloth and clothing items and a manufacturing method and systems thereof are conventional fiber materials such as viscose and polyamide, which do not require additional processing, thus the fabrics produced have stable properties and are not prone to decrease in cool feeling due to multiple washings. Furthermore, alternative yarn materials are relatively cheap, and thus the cost of the produced fabric with cool feeling is low.
